Door design refers to the process of creating and planning the appearance and functionality of doors. This includes considerations such as materials, styles, and sizes. Common materials used in door design include wood, metal, and fiberglass, each offering different aesthetic and durability qualities. Additionally, door design can encompass various styles, such as traditional, modern, or rustic, allowing homeowners to choose options that complement their overall decor. Functional aspects, like security features and energy efficiency, are also important, ensuring that doors not only look good but also serve their purpose effectively.
